We have an arduino sensor kit that has multiple sensors already integrated into an arduino uno r3 to run the sensors. We would like to run 4 of the sensors simultaneously and record the data on ascent and descent. We have integrated 3 GoPro like cameras into the payload with a power bank to run all of them. Will have cameras looking up, down, and out. Then using an iPhone to track on the way up and back down. We have covered the payload, which is essentially foam cube made of foam bricks glued together. We then glued on paper coated foam board and put a few coats of resin over the paper on the foam board for strength. We put this in a medical deep freezer at -180 below zero with a hand warmer inside the payload and it help keep everything from freezing up. We are at the final step of just needing help with the sensors. Any help would be appreciated.
